摘要: 碳纤维复合材料(CFRP)被广泛应用于航空领域飞行器结构和部件的制造。由于飞机经常会在一些恶劣条件下工作,碳纤维表面涂层会老化失去原有的性能,飞机服役年份越久,所需剥离涂层厚度越深。采用CO2激光器对CFRP表面涂层进行了定量剥离研究来代替传统机械打磨。实验结果表明,在一定误差允许的范围内,20 W、25 W和30 W的功率下分别能够实现预设的5 μm、10 μm、20 μm的去除量剥离的要求;此外,材料力学性能未出现削弱,满足重新涂装的要求。

Abstract: Carbon fiber composite material (CFRP) is widely used in the manufacture of aircraft structures and components in the aviation field. Because aircraft often works in some harsh conditions, the surface coating of carbon fiber will age and lose its original performance. The longer the aircraft is in service, the deeper the coating needs to be removed. The coating of CFRP was quantitatively peeled by CO2 laser instead of the traditional mechanical grinding. The experimental results show that the preset requirements of 5 μm, 10 μm and 20 μm removal can be achieved under the power of 20 W, 25 W and 30 W, within a certain error permissible range. In addition, the mechanical properties of the material are not weakened, which meet the requirements of recoating.
